The RAM X-Grip universal holder for 12" tablets features an 'X' design that expands and contracts to provide a perfect fit for your device – even if it's in a case. Included are easy access grip knobs located on the back of the cradle for quick release of your tablet. No matter what double socket arm and mounting base you pair the RAM X-Grip with, RAM ball and socket technology allows for near-infinite adjustability to achieve the ideal viewing angle – while also extending the life of your tablet by providing shock and vibration damping. This version of the RAM X-Grip holder is compatible with tablets that will fit the dimensions listed below. It is important to verify the dimensions of device with its case, sleeve, or skin when determining the overall size.
